ABB 1SDA116363R1 Moulded Case Circuit Breaker - IEC

The four-pole moulded-case construction provides coordinated protection across all phases, reducing cross-phase fault risk and wiring mistakes in control cabinets. This yields faster fault isolation and lower annual maintenance costs, particularly in high-density power distribution panels. The adjustable setting range of 87.5 to 125 A with an instantaneous trip of 1250 A enables selective coordination and fast fault clearance for motor feeders, minimizing outages in facilities with variable loads. High short-circuit ratings—I_cs up to 50 kA at 240 V AC and 36 kA at 380–440 V AC, with I_cu up to 70 kA—support safe fault handling in demanding environments, translating to improved plant availability. The unit’s 6.60 W power loss contributes to reduced enclosure heat and easier thermal management, while its 20,000 mechanical cycles durability ensures long life in busy production lines. Front-terminal wiring simplifies installation and retrofits, enabling quicker commissioning and more reliable panel layouts. RoHS/REACH declarations, TSCA readiness, and CMRT support regulatory compliance and transparent sourcing for regulated industries. The compact footprint (140 mm width, 150 mm height, 70 mm depth) and 2 kg weight aid enclosure planning and logistics for OEMs and integrators.
